SlPHON-BOTTLE.

SPECIFICATION forming part of Letters Patent No. 578,094, dated March 2,1897.

Application filed September '7, 1895. Serial No. 561,860. (No model.)

To all whom t may concern:

Be it known that I, GEORGE CoRBToN, J r., a citizen of the United States, residing in the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Siphon-Bottles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to bottles, having reference more especially to that class of bottles termed siphon, in which aerated or carbonated waters are contained, my object being mainly to provide a construction whereby the bottles may be more expeditiously and effectively charged than heretofore, whereby their uses may be extended to a wider range of liquids, and whereby 'the bottles may be readily and thoroughly cleansed without the necessity of removing the Siphon-heads therefrom, as will be hereinafter particularly described and claimed.

In the annexed drawings, Figure l is a longitudinal central section of a Siphon-bottle embodying my invention in a simple and efficient form. Fig. 2 is a plan thereof. Fig. 3 is a vertical section of the Siphon-head as on the line 0c of Fig. 2. Fig. 4 is a partial longitudinal central section of a modification.

A designates a bottle of proper shape and size for its intended purpose. The bottle herein shown is similar in form to an ordinary Siphon-bottle, excepting that it is provided with an opening a in the center of its bottom and with a valve a' to seal the opening, as will hereinafter appear.

Screwed to a split collar on the neck of the bottle or otherwise secured to the bottle is a Siphon-head B, which is provided With the usual discharge-nozzle l) and with a depending tube b', that leads therefrom to the bottom of the bottle, or nearly so. The head is also provided with a suitable release-valve b2, (preferably of the character below described, that opens or closes the communication between the nozzle and the tube, as desired. In the top of the head is formed a chamber b3,t.hat communicates with the interior of the bottle by means of channels b4 on the respective sides of the valve -chamben Surmounting the head is a screw-collar b5, tothe inner edge of which is fitted an annular gasket b, while within the chamber is contained a seal b7,pref erably a spherical ball, `which is adapted to be seated against the gasket by the pressure of the confined gases within the bottle, so as to hermetically seal the opening.

In the side of the siphon-head, at a point below the release-valve, is a vent or passage 68, which is normally closed by a springcon trolled valve b9, the stem of which projects exteriorly of the head, as seen, whereby pressure may be readily applied to the valve to open the passage for a purpose below explained Siphon-bottles as heretofore constructed have been filled upside down by especial apparatus, through and by way of the dischargenozzle and the inner tube, thereby requiring to till or charge the bottle about double the pressure required to discharge it. This is owing to the necessarily small delivery-channel, which, moreover, precludes the use of siphonbottles for beers or any beverages containing Syrups, compounds, or foams, and, in consequence, the use of the bottles is restricted to soda, artificial or natural spring and mineral waters that do not foam under pressure. By the construction herein these objections are obviated, since :in order to fill the bottle (assuming the release-valve to be closed) it is merely requisite to introduce the beverage by Way of the chamber b3, the valve therein, when the bottle has been charged, being automatically pressed against its seat by the pressure ofthe confined gases, as above mentioned.

Another objection to the prior construction is that in order to effect the escape of thecom pressed air within the bottle during the charging process it has been necessary to cease the operation and permit the air to escape by way of the tube and nozzle, and such escape being more or less uncertain bottles of extraordinary strength were required. By my construction, however, the sniffing, as it :is termed, may be expeditiously and efectively carried on during the actual charging of the bottle, the valve b9 being merely pressed from time to time to open the vent or passage.

Another objection to the previous construc IOO tion is that the bottle cannot be washed out without the necessity of removing the siphonhead, which is only done with considerable skill, difficulty, and great waste of time. This objection is avoided by the bottom opening a. The valve for this opening comprises an elongated head provided with a gasket a2 thereon, the head being constructed to t the opening and the gasket to bear upon the edge of the latter. The valve normally enters the opening, and the pressure of the confined gases on the valve insures an effectual sealing of the opening.

In some instances, particularly where an ordinary Siphon-head is employed, the bottle may be charged by way of the bottom opening, the snifting operation thus being effected through the manipulation of the release-valve.

If desired, the bottom of the bottle may comprise a detachable metal cap or base provided with a central opening therein.

As to the release-valve b2, while it may be of the usual construction, that is, longitudinally reciprocative in respect to the bottle, I prefer to use with my improved siphon-head a horizontally-reciprocative valve that is operated by means of a spring-controlled thumblever blo on the head. Vhere the valve is vertically reciprocative, it is subjected directly to the pressure ot' the confined gases, and hence a comparatively powerful spring is required to counteract the pressure; but where the valve is transversely movable, as in this instance, the tendency of the gases to open the valve is avoided, and hence a comparatively light spring is required, and in consequence slight manual power is required to open the valve.

In Fig. 4 is shown a slight modification of the invention wherein the chamber b3 in the top of the Siphon-head communicates by a single direct passage with the interior of the bottle, the seal bl beinga disk valve which is yieldingly held to its seat by means of a suitably-disposed spring b and the release-valve being a rotary instead of a sliding one. In this construction the shifter-valve is shown as applied directly to the body of the bottle instead of to the Siphon-head.

Obviously the invention may be otherwise modified to meet particular requirements.
